Collectible coins, particularly those from the United States, encompass a wide range of types, including patterns, which are experimental or trial pieces created to test new designs or technologies before mass production. The 1864 patterns, specifically related to the Lincoln cent, are notable for their historical significance, as they represent a transition in U.S. coinage design during the Civil War era. These coins are highly sought after by collectors due to their rarity, unique features, and the artistry involved in their creation. The value of such collectible coins can vary dramatically based on their condition, provenance, and market demand.
